RADIATOR-TRUCK.

SPECIFICATION forming part of Letters Patent No. 530,437, dated December 4, 11894.

Application ledSeptemher 15, 1894. Serial No. 523,111- (No model.)

proved Radiator-Truck, of which the following is a full, clear, and exact description.`

The object of the invention is to provide a new and improved truck, more especiallydesigned for conveniently and easily moving radiators to their places in finished houses Without danger of injuring the woodwork,

' walls or Aother parts ofthe houses.

The invention consists principally ofv a truck frame having side legs adapted to be connected with each other by a cross bar, and detachable chains adapted to engage the top and the base of the radiator, the said chains extending from one side leg to the other.

The invention further consists of a side leg having a slidable caster and a gravity locking device for locking the extending casterin place.

The invention also consists of certain parts and details and combinations of the same as will be fully described hereinafter and thon pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part ot this specification,

in which similar letters of reference indicate corresponding parts in all the gures.

Figure l is a perspective view of the improvement as applied. Fig. 2 is an end view of the same. Fig. 3 is a side elevation of one of the sidelegs with parts in section; and Fig. 4 is a similar View of the same with the parts in a different position For large sized radiators two trucks A, alike in construction, are employed and are applied as illust-rated in Fig. l, but for smaller radiators one truck vwill be sufficient. Each truck A is provided with two side legs B and B', made T-shaped with horizontal arms B2 formed at one end into a handle to be taken hold of by the operator, as hereinafter more fully described. The two legs B and B are adapted to be connected with each other at the handles of the horizontal arms B2 by a cross bar C held in place by removable keys D, as is plainly indicated in the drawings.

On the outer end of the horizontal arms B2 of one side leg B is securedachainE adapted to be passed over the top of the radiator to 4 be hooked on a hook arranged on the outer end ofthe other side leg B, and a similar chain F is attached to the vertical arm or post B3 of one side leg, to be passed under the base of the radiator and hooked on a hook of the vertical arm or post B3 of the other side leg. In each postBS, and at the lower end thereof, is arranged a slidable caster formed with a shank H, fitted to slide in. suitable bearings in the lower end of the post, the said shank carrying at its lower end thecaster wheel H adapted to travel on the door of the shank, to limit the downward sliding of the t caster, as is illustrated in Fig. 4c.

The upper end ot' the shankHextends into T a recess B4 formed in the post B3 and the top of the shank is adapted to be engaged by a gravity pawl I fulcrumed at I in the recess B4, the said pawl being provided with a handle arm I2 adapted to be taken hold of by the operator to swing the gravity pawl out ot' contact with the upper end of the shank H when it is desired to lower the radiator to its place, as hereinafter more fully described. Atransversely extending pin 13 passes through the t recess B4 to limit the downward swinging of the pawl I, to properly engage the latter with the upper end of the shank H.

The operation is as follows: When the radiator rests on the ioor and is to be transported to the proper place in the room of the building, then two trucks are applied,one on each end, by passing the side legs ot' each truck on the end until the cross bar C rests against the end of the radiator with the handle arms ot' the said legs extending from the respective end, and when the. operator takes the top chain E and passes it over the radiator top to hook it on the other side leg, as

IOO

When this has been done the operator 1 so that the shaft H of the casters in the posts B3 slide downward, the wheels H remaining on theY floor until-inally the shanks H are in their lowermost position, as indicated in Fig. 4, and the pawls I have swung into a vertical position to form a lock for the said shank H, and to prevent the latter from sliding up-` ward. The operator now releases the handles and applies the other truck on the other end of the radiator, whereby the radiator is flnally suspended above the tloor in the two trucks, to permit the operator to conveniently wheel the truck with its load to the place where the radiator is to be set up. When at or near the place of its destination the operator lifts the handle ends of one truck and swings the gravity pawls I upward, to disengage the same from the Shanks H, so that when the operator lowers the handles the shanks H will slide upward in their bearings in the posts B3 untiltinally the legs of this end of the radiator rest on the floor. The same operation is then repeated at the other end of the radiator so that this end is lowered and the entire radiator is supported on the Iioor. The trucks arethen removed by unhooking the chains E and F from one side leg and pulling the trucks away from the ends of the radiator.

The shanks H can be locked in an uppermost position by` giving a quarter turn to the Shanks, so as to engage the pins H8 with notches B4 in the posts B3. See Figs. 3 and 4.

Having thus fully described my invention, Iclaim as new and desire to secure by Letters Patentl. A radiator truck comprising two side legs, a cross bar for connecting the said legs with each other, and chains secured at one end to one of the side legs and adapted to be passed over the top of the radiator and under the base of the radiator to be hooked on .the-other side leg, substantially as shown and described.

2. A radiator truck provided with side legs connected with each other, and a slidable caster held in each side leg and adapted to be locked in position therein, substantially as l shown and described.

3. A radiator truck provided with a truck frame having two connected side legs, a caster held eXtensibly in each side leg and a locking device on each side leg for fastening the caster in an extended position, substantially as shown and described.

4. Aradiator truck comprisinga frame having two connected side legs, a caster fitted to slide in the vertical part of each side leg, and

a gravity pawl hung in the said side leg and adapted to engage and lock its caster in an extended position, substantially as shown and described.
